Method and apparatus for IP encapsulated tandem hard handoff in CDMA networks

摘要

A method and apparatus in a mobile switching center (MSC) performs a tandem handoff in a wireless communication network. The serving MSC receives a handoff request from a serving base station (BS) for a handoff to a target BS of a target MSC. When the serving MSC does not have physical handoff trunks, the serving MSC sends a tandem handoff request to a tandem MSC.
